Abstract (en)
[origin: EP0957615A2] A method for obtaining a reliable estimate of the transmitter clipping error compliant with T1.413 ADSL standard is disclosed. An architecture (110) is disclosed that uses the clipping error estimate at the receiver to reconstruct a frequency-domain compensation signal (EÄkÜ). The method for computing the compensation signal is disclosed along with an asymmetric digital subscriber line modem supporting T1.413 standard transmission/reception functions over a discrete multi-tone communications system capable of estimating clipping errors and computing clipping compensation signals. <IMAGE>
